  The SAP error message CNV_IUUC_REPL_ADV_SE005 with the description "Select exactly one row" typically occurs in the context of data replication or migration processes, particularly when using the SAP Landscape Transformation (SLT) or SAP Data Services. This error indicates that the system expected a single row to be selected from a database table or a result set, but either no rows or multiple rows were returned.
  Causes:
  
  Multiple Rows Returned: The query or selection criteria used in the process returned more than one row when only one was expected.
  No Rows Returned: The query did not return any rows, which can also trigger this error in certain contexts.
